LOOM-PICKER-STICK CHECK.

Application filed ctober S, 1919.

To all-whom t may concern.'

Be it known that I, VALTER WV. Hns'rLnY, a citizen of the United States,residing at Greensboro, in the county of Guilford and State of NorthCarolina, have invented certain new and useful Improvements in Loom-Picker-Stick Checks, of which the following is a specification.

The invention relates to a loom picker stick check device, andi moreparticularly to the class of tensioned manually adjustable picker stickchecks for use in looms.

The primary object of the invention is the provision of a check` deviceof this character, wherein the same is mounted beneath the lay of aloomat the point of the shuttle box therein, so as to be disposed relativeto the movable picker stick to retard the movement of said stick in onedirection, the check device being of novel construction to permit manualadjustment thereof for the taking up of wear thereon or increase ordecrease the checking action thereof upon the picker stick.

Another object of the invention is the provision of a check device ofthis character, wherein the same is constructed to eliminate the use ofleather or other like material, as is commonly employed in looms for thechecking of the picker stick, thereby avoiding` the frequent replacementof the lea-ther check and repairs thereto as is usual in the usethereof.

A further object of the invention is the provision of a check device ofthis character, wherein the same can be readily ar-.

ranged upon various styles of looms employing picker sticks forimparting motion to the shuttle in the process ofV weaving and willautomatically operate to check the picker stick, as the said check is atall times under tension and is disposed relative to the path of movementof the picker stick to act directly thereon for checking purposes.

A still further object of the invention is the provision of a checkdevice of this character, wherein the checking arm or member issupported for adjustment to vary the checking action thereof and thesame is supported beneath the lay upon the fastener securing the shuttlebox thereto, thereby avoiding the necessity of changing the constructionof the loom or requiring any alterations thereto for the attachment ofthe check device upon its lay.

A still further object of the invention is Specification of LettersPatent.

Patented Apr.,13, 1920.

serial No. 328,708.

the provision of a check device of this character, which is extremelysimple in construction, thoroughly reliableand efficient in its purpose,readily and easily adjusted, capable of being applied to a loom withoutrequirinf skilled labor and also inexpensive to manufacture and install.

lith these and other objects in view, the invention consists in thefeatures of construction, combination and arrangement of parts, as willhereinafter be fully described, illustrated in the accompanying drawingand pointed out in the claim hereunto appended.

In the accompanying drawing:

Figure l is a fragmentary plan view of the lay and shuttle box of aloom, showing the shuttle therein and a shuttle check, with the pickerstick check constructed in accordance with the invention, applied to theunder side of the lay for checking action on the picker stick.

Fig. 2 is a fragmentary elevation, the parts being reversed with respectto their position shown in Fig. l.

Fig. 3 is a fragmentary plan view of the checking arm, showing in detailthe adjusting eccentric, the pivot bolt or fastener being in sections.

Fig. 4 is perspective view of the adjusting eccentric removed.

Fig. 5 is fragmentary sectional view on the line 5-5 of Fig.. 2.

Fig. 6 is a fragmentary bottom plan view.

Similar reference characters .indicate corresponding parts through theseveral views in the drawing.

Referring to the drawing in detail, A designates generally a portion ofthe lay of a loom, which is constructed with the race, as usual, for theshuttle B, the same being of ordinary well-known construction and uponthe lay is located the shuttle box C having mounted at one side thereofa shuttle check A l) of any approved type for the shuttle when receivedin the shuttle box C at the limit of its movement in the race upon thethe present invention, comprises a checking arm 5, preferably made fromhard wood, although the same may be made from any other material iffound desirable and is of the required length, having formed on itslonger side diagonally disposed checking surface 6, relative to theopposite straight longer edge 7, the arm near one end being formed witha suitable hole for accommou dating an adjustable eccentric. Theadjustable eccentric comprises an eccentric sleeve 8 adapted to snuglylit in the hole near one end of the arm 5 and is mounted upon a bolt 9,which is passed through the lay A and secures the shuttle box C thereon,the bolt being passed through the longitudinal opening 10 eccentricallyformed in the eccentric sleeve 8, which is provided with an annularexternal flange or enlarged hub 11 at one end thereof for a purposepresently described.

The checking arm 5 is disposed longitudi,n nally of the lay at theunderside thereof beneath the shuttle boX C and is pivotally supportedfor swinging movement upon the eccentric sleeve 8, which is carried uponthe bolt 9, passed through the lay A and connecting the shuttle boXthereto, the hub or iange end ll of the eccentric sleeve 8 being locatednext to the nut 12 upon the bolt 9, c

so as to provide a turn-table for the checking arm 5 as said flange orhub 11 serves as a shoulder portion for movably supporting the arm 5 topermit the same to move inwardly toward the path of movement of thepicker stick E whereby the diagonal checking surface 6 of the said armwill contact with the picker stick when moved for actuating the shuttlel5 and thereby checking the picker stick on movement thereof 1n onedirection.

The flange or hub 11 of the eccentric sleeve 8 has formed therein asocket 13 for accommodating a spanner to permit the manual adjustment ofthe eccentric sleeve 8 to shift the arm 5 the required distance towardor away from the slot accommodating the picker stick E in the klay A ofthe loom, so as to vary the checking action of the arm 5 upon saidpicker stick.

Secured to the side of the lay A upon which the checking arm 5 ismounted is a.

bowed leaf spring 14, the same being secured at one end while itsopposite end is free and plays against the straight longer edge 7 of thearm 5 to tension the latter and constantly move it inwardly in the pathof movement of the picker stick E so as to check the movement thereofwhen active upon the shuttle B to advance the same in the race on thelay A of the loom.

The spring 14 constantly maintains a tension upon the arm 5 to assurethe checking of the picker stick in its movement in one direction and tohold the said arm 5 in operative relation to the picker stick, theadjustable eccentric being manually operated to move the arm for thetaking up of wear upon said arm or the picker stick during the operationof the loom.

The check device, as hereinbefore described, will take the place ofleather checks for picker sticks, as commonly employed in looms, therebyeliminating the use of leather as a check and also minimize repairsincident t0 the use of such leather checks.

Mounted near the free end of the check arm 5 and suitably fastened tothe lay A is a guide bracket 15 in which the free end portion of saidarm works and this bracket serves also as a stop to limit `the inwardswinging movement of the free end of said check arm toward the movementof the picker stick E and also this guide bracket 15 prevents thesagging of the free end portion of the arm and guides it in its movementwhen active for checking of the picker stick.

It is thought that the construction, manner of mounting and theoperation of the check device will be clearly understood and, therefore,a more extended explanation has been omitted. However, it iscontemplatedthat changes, variations and modifications may be made in the inventionas come properly within the scope of the appended claim withoutdeparting from the spirit of the invention or sacrificing any of itsadvantages.

What is claimed is:

' A picker stick check of the character described, comprising a swingingarm, a des tachable pivot bolt adapted to be carried in and dependingfrom the lay of a loom, an eccentric rotatably supported on the bolt,engaged in the arm and having a lower circular flange forming aturntable for the arm, and means for tensioning said arm.

In testimony whereof, I have hereunto affixed my signature.

WALTER W. HESTLEY.
